No, it's because they're sick and tire of all your kind's whining, demands and terroristic tactics. That city is no longer a safe place with so many ferals. You want Ferguson, you can have it. When the cracker police force walks away, it'll be worse than Chicago on a Saturday night 24/7. If there is any Ferguson cop who doesn't have his resume sent out to a dozen other locations by now, he's certifiable.
That is how these problems are avoided here in the northeast; the police “stand down” (AKA “de-police”), and let them have at each other. Given the number of unassimilated gibsmedats here, we have very few issues like this. They tried to fabricate a couple, but it didn’t really take.
Another solution is the expulsion of gibsmedats if there is any value in an area; this is occurring in Brooklyn NY and Jersey City NJ.
